Low power system and method for DSL lines
The transmit power level of a transceiver coupled to a digital subscriber line (DSL) line is reduced from a first transmit power level sufficient for the transceiver to continuously transmit data on the DSL line at a first bit rate to a second transmit power level below the first transmit power level sufficient for the transceiver to continuously transmit data on the DSL line at a second bit rate that is lower than the first bit rate. The reduction in transmit power is limited so that the change does not induce time-varying crosstalk sufficient to destabilize a nearby DSL line. While the transmit power level of the transceiver is reduced to the second transmit power level, the transceiver is suspended from transmitting data on the DSL line for repeated periods of time. Suspending the data transmission is controlled to avoid further time-varying crosstalk sufficient to destabilize the nearby DSL line. |

Aggregation of encrypted data
In some embodiments, an encryption system secures data using a homomorphic encryption. The encryption system encrypts a number by encrypting a number identifier of the number and combining the number and the encrypted number identifier using a mathematical operation to generate an encrypted number. The encrypted numbers may be stored at a server system along with their number identifiers. The server system can then generate an aggregation (e.g., sum) of the encrypted numbers and provide the aggregation, the encrypted numbers, and the number identifiers. The encryption system can then separate the aggregation of the numbers from the aggregation of the encrypted numbers using an inverse of the mathematical operation used in the encryption to effect removal of an aggregation of the encrypted number identifiers of the numbers from the aggregation of the encrypted numbers. The separated aggregation of the numbers is an aggregation of the plurality of the numbers. |

Battery capacity degradation resolution methods and systems
A vehicle can include a traction battery and a controller in communication with the battery to determine the battery state using sensed battery electrode capacity to account for battery aging. The sensed battery electrode capacity can be dependent on active lithium ions at a positive electrode of the traction battery. The controller can compare a battery voltage model to measured battery voltage during a vehicle drive cycle, receive sensed current throughput data and open circuit voltage at the battery, and determine if a deviation threshold is exceeded. The controller can also correct electrode capacity using a mean of the measured open-circuit voltage to correct the capacity error to less than one amp-hour or initiate an active lithium capacity correction using a variance of the current throughput to correct the capacity error to less than one amp-hour. This information can be used to control the vehicle and battery usage. |
